Abstract
The invention provides a bactericidal composition containing chlorofluoromethane and tebuconazole, wherein the weight ratio of the chlorofluoromethane to the tebuconazole is 1: 10-10: 1. The composition of the invention has obvious synergistic effect, can reduce the dosage of medicament, reduce cost, reduce harm to environment and is beneficial to the generation of drug resistance.
Description
Technical Field
The invention belongs to the field of agricultural chemistry, and particularly relates to a bactericidal composition containing chlorofluoromethane and tebuconazole.
Background
The meperfluorfen-azole (Mefentrifluconazole) is a novel isopropanol triazole bactericide which has broad spectrum, high efficiency and systemic effect and has the functions of eradicating and protecting, and belongs to the sterol demethylation inhibitor. Different from the widely used triazole bactericide, the cloroxen difenoconazole contains an isopropanol structure, can reduce the mutation of pathogenic bacteria, delay the drug resistance of the pathogenic bacteria and is beneficial to delaying the generation and development of the resistance of the bactericide; the product has been registered in countries and regions such as China, Australia, Canada, the United states, Korea, and the European Union, and the registered crop is more than 40.
Tebuconazole is a systemic fungicide with protective and therapeutic effects, can be quickly absorbed by the growing parts of plants and mainly transferred to the top. Tebuconazole has bactericidal activity, can promote the growth of crops, enables the roots of the crops to be developed, leaves to be dark green, plants to be robust and effective tillering to be increased, thereby improving the yield, has the advantages of strong systemic property, high drug effect, safety and long lasting period, and can be used for preventing and treating rust disease, banded sclerotial blight, powdery mildew, net blotch, root rot, wheat scab and the like of cereal crops.
The compounding of different kinds of components is a common method for preventing and treating resistant diseases. Different components are compounded, whether the compounding is synergistic, additive or antagonistic is judged according to the effect of practical application, and the compounding has a good synergistic formula. In the prior art, no report is provided about the combination of the chlorofluoromethrin and the tebuconazole.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the following technical scheme:
the active ingredients of the bactericidal composition comprise the chlorofluoromethrin and the tebuconazole, and the weight ratio of the chlorofluoromethrin to the tebuconazole is 10: 1-1: 10.
The preferred weight ratio of the fluroxypyr to the tebuconazole of the bactericidal composition is 1: 5-5: 1.
The bactericidal composition also comprises agriculturally acceptable auxiliaries, and the weight percentage of the active ingredients is 5-90%. The auxiliary agent comprises a dispersing agent, an emulsifying agent, a disintegrating agent, a stabilizing agent, an antifreezing agent, a wetting agent, a synergist, a penetrating agent, a filler and a solvent.
The dosage form of the bactericidal composition provided by the invention is wettable powder, water dispersible granules, emulsion in water, granules, missible oil, suspending agent and the like.
The bactericidal composition is used for preventing and treating crop diseases. In particular to the prevention and the treatment of rice sheath blight and strawberry gray mold.
When the composition is further used for rice sheath blight, the weight ratio of the fluroxypyr to the tebuconazole is 1: 10-5: 1. When the bactericidal composition is used for strawberry gray mold, the weight ratio of the fluroxypyr to the tebuconazole is 1: 5-5: 1.
Compared with the prior art, the invention has the following beneficial effects:
the bactericidal composition disclosed by the invention is composed of two active ingredients with different action mechanisms, has an obvious synergistic effect after being mixed, improves the control effect, and is also beneficial to overcoming and delaying the generation of drug resistance of diseases.
The composition of the invention is mixed with pesticide to reduce the dosage, thereby reducing the cost and lightening the pollution to the environment, having good safety and meeting the safety requirement of pesticide preparations.
Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
EXAMPLE 1 determination of indoor toxicity of Chlorofloxacin and Tebuconazole on Rhizoctonia solani
Test subjects: the rhizoctonia solani is obtained by the company through collection, separation and purification from the field.
The test method comprises the following steps: a PDA culture medium is used for carrying out a preliminary test, then a mother solution with a proper concentration of a reagent to be tested is diluted by sterile water and is uniformly mixed with the sterilized PDA culture medium, a medicine-containing culture medium with a medicine concentration in an equal ratio gradient is prepared, and the medicine-containing culture medium and the sterilized PDA culture medium are respectively poured into a culture dish for later use. And intercepting the pathogenic bacteria cake to be used cultured on the PDA culture medium by using a puncher, inoculating the pathogenic bacteria cake to the center of the solidified PDA culture medium containing the medicine, culturing at 26 ℃, and measuring the diameter of the colony by using a caliper when the diameter of the control colony is larger than the diameter of a flat dish 2/3. The diameter of each colony was measured perpendicularly 1 time by the cross method, and the average value was obtained. Each treatment was repeated 4 times and the growth inhibition of colony expansion by each agent treatment was calculated in comparison to the control. The logarithmic value of the mass concentration of the drug was set as the abscissa and the value of the number of the hypha growth inhibition ratio was set as the ordinate, and the test data was analyzed by the regression analysis method to calculate the EC50 value for each treatment.
Calculating the virulence index and the cotoxicity coefficient (CTC) of the medicament according to the Sun Yunpei method. When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
And (3) test results: TABLE 1 indoor toxicity determination of Chlorofloxacin and Tebuconazole on Rhizoctonia solani
Conclusion and discussion: as shown in Table 1, the bactericidal composition of the invention has the weight ratio of the meperfluthrin to the tebuconazole within the range of 1: 10-10: 1, and has synergistic and additive effects on rice sheath blight; the weight ratio of the chlorofluoromethrin to the tebuconazole is within the range of 1: 10-5: 1, the synergistic effect is shown on the rice sheath blight disease, particularly, the weight ratio of the chlorofluoromethrin to the tebuconazole is within the range of 1: 1-5: 1, the obvious synergistic effect is shown on the rice sheath blight disease, and the CTC value is more than 130.
Example 2: indoor toxicity determination method of chlorofluoromethane and tebuconazole on strawberry gray mold
Test subjects: the botrytis cinerea is obtained by the company through field collection, separation and purification.
The test method comprises the following steps: a hypha growth rate method (a specific configuration method refers to example 1) and a CTC method are adopted for evaluating the synergistic effect.
